STUDY DESIGN: A retrospective study. OBJECTIVE: To determine the definite cut-off value of initial correction rate (ICR) that could be predictive of bracing outcome in patients with adolescent idiopathic scoliosis. SUMMARY OF BACKGROUND DATA: Earlier studies showed that braced patients with a better ICR could finally have a higher probability of successful outcome. However, it remains controversial what definitive cut-off value of ICR is required to accurately predict the outcome...

Lytic polysaccharide monooxygenases of family AA9 catalyze the oxidative cleavage of glycosidic bonds in cellulose and related polysaccharides. The N-terminal half of AA9 LPMOs displays a huge sequence variability that is in contradiction with the substrate simplicity so far observed for these enzymes. To understand the cause of the high multigenicity that prevails in the family, we have performed a clustering analysis of the N-terminal region of 3400 sequences of family AA9 LPMOs, and have evaluated the coincidence of the clusters with distal visible features that may accompany functional differences...

BACKGROUND: This study was performed to determine if the effectiveness of patellofemoral bracing as a treatment for patellofemoral osteoarthritis is influenced by patellofemoral joint alignment and trochlear morphology. We hypothesized that those with more extreme patellar malalignment would benefit more from bracing. METHODS: Thirty-eight patients who had received bracing as part of a comprehensive treatment plan for patellofemoral osteoarthritis were selected for this study...

Chromatin remodellers are helicase-like, ATP-dependent enzymes that alter chromatin structure and nucleosome positions to allow regulatory proteins access to DNA. Here we report the cryo-electron microscopy structure of chromatin remodeller Switch/sucrose non-fermentable (SWI2/SNF2) from Saccharomyces cerevisiae bound to the nucleosome. The structure shows that the two core domains of Snf2 are realigned upon nucleosome binding, suggesting activation of the enzyme. The core domains contact each other through two induced Brace helices, which are crucial for coupling ATP hydrolysis to chromatin remodelling...

Fractures of the upper limbs are frequent and often need operative treatment in addition to a well-indicated conservative management. This depends on the maturity of the nearest growth plate and the local remodeling potential, which is dependent on age. Following conventional x‑ray imaging an individual prognostic growth analysis leads to the therapeutic decision. Around the elbow and the shaft of the forearm, criteria are stricter than near the shoulder or wrist. Gilchrist or Desault bandages as well as braces are adequate for most subcapital and humeral shaft fractures...

The superfamily 1B (SF1B) helicase Sen1 is an essential protein that plays a key role in the termination of non-coding transcription in yeast. Here, we identified the ~90 kDa helicase core of Saccharomyces cerevisiae Sen1 as sufficient for transcription termination in vitro and determined the corresponding structure at 1.8 Å resolution. In addition to the catalytic and auxiliary subdomains characteristic of the SF1B family, Sen1 has a distinct and evolutionarily conserved structural feature that "braces" the helicase core...

BACKGROUND: A temperature monitor is used to objectively measure brace wear time in adolescent idiopathic scoliosis. The reliability of this device have been demonstrated, and some specialists introduced the use of a compliance monitor as a standard of care in everyday clinical practice, as we did since 2010 with the Thermobrace (TB). The attitude towards these objective monitors has never been investigated. The present study aims to investigate the attitude of parents and patients towards the use of temperature sensors for measuring brace wear compliance...

There are at least two reasons to study traits that mediate successful range expansions. First, dispersers will found new populations and thus impact the distribution and evolution of species. Second, organisms moving into new areas will influence the fate of resident communities, directly competing with or indirectly affecting residents by spreading non-native or spilling-back native parasites. The success of invaders in new areas is likely mediated by a counterbalancing of costly traits. In new areas where threats are comparatively rare, individuals that grow rapidly and breed prolifically should be at an advantage...

 Selective dorsal rhizotomy (SDR) has been used to treat children with spastic cerebral palsy (CP) for over three decades. However, little is known about the outcomes of childhood SDR in adults.  Objectives: 1) To study the effects of childhood SDR on the quality of life and ambulatory function in adult life. 2) To determine late side effects of SDR in adults.   Methods: Adults (> 17.9 years) who underwent SDR in childhood (2 - 17.9 years) between 1987 and 2013 were surveyed in 2015. Patients completed a survey, including questions on demographic information, quality of life, health, surgical outcomes, motor function, manual ability, pain, braces/orthotics, post-SDR treatment, living situation, education level, work status, and side effects of SDR...

Scoliosis is a common medical problem, with an incidence of between 0.47% and 5.2% in the general population globally. Adolescent idiopathic scoliosis (AIS) accounts for nearly 80% of all scoliosis. Young people with AIS often experience negative social consequences in association with their condition. Without proper and timely treatment, the potential resulting disabilities range from trunk deformity, pain, and neurological complications to compromised cardiopulmonary function, all of which may cause lifelong suffering...

Po-Hung Wu, Zachary Borden, Chris L Brace
PURPOSE: Intra-procedural contrast-enhanced computed tomography (CECT) has been proposed to monitor the growth of ablation zone in order to evaluate the efficacy of microwave ablation more accurately than post-ablation image. However, the dilemma of keeping image quality or following dose regulation becomes a huge challenge to apply CECT in real-time monitoring. The purpose of this study is to evaluate the feasibility of applying local highly constrained backprojection reconstruction (HYPR-LR) on periodic CECT image to enhance visualization of ablation zone by statistical and pathological- radiological analysis...

PURPOSE: This study aimed to investigate the treatment effects of low-intensity pulsed ultrasound (LIPUS) on progressive-stage spondylolysis. Spondylolysis is a stress fracture of the pars interarticularis. Based on the results of computed tomography, spondylolysis was classified into three categories: early, progressive, and terminal. Bone healing was prolonged or not obtained in progressive-stage spondylolysis. The progression of spondylolysis to nonunion has been associated with an increased incidence of spondylolisthesis...

Ankle braces are a common treatment to reduce ankle sprain recurrence among individuals with chronic ankle instability (CAI). Bracing provides supplemental external joint stiffness and/or improved proprioceptive acuity. The goals of this study were to assess the effects of two ankle braces on joint position sense (JPS) and ankle stiffness, and determine whether bracing effects are reduced with localized muscle fatigue. Measures of JPS and ankle stiffness were obtained from participants with CAI (n=12) for three conditions (no brace, a neoprene wrap brace, and a semi-rigid brace), before and after inducing localized muscle fatigue at the ankle...

BACKGROUND: The primary treatment strategy for chronic atlantoaxial rotatory fixation (chro-AARF) is traction followed by bracing or application of a Halo device. However, to complete these conservative therapies, patient cooperation is mandatory. If conservative therapy fails, surgery is required for reduction and prevention of recurrence. It has been considered that surgery for AARF necessitates solid bony fusion. However, once bony fusion is achieved, loss of range of motion is problematic...

BACKGROUND: The therapeutic efficacy of serial casting on idiopathic scoliosis has been gradually documented. However, literatures on serial casting for congenital scoliosis (CS) remain extremely rare. This paper aimed to compare the treatment outcomes of serial casting between CS and non-CS patients to comprehensively evaluate the therapeutic characteristics of serial casting on CS patients. METHODS: A total of 23 early-onset scoliosis cases were included and divided into congenital scoliosis (CS, n = 8) and non-congenital group (non-CS, n = 15)...
